I retrofitted a 10p display from an explorer into my Taurus. In my efforts of doing so I had to flip the APIM 180 degrees with the connector facing the cabin. After doing so my GPS is not accurate at all. I thought I remember reading somewhere that there is an asbuilt value for the physical orientation of the APIM. That could have been a sync 4 thing I read though. Anyone have any ideas? Looking at the sync 3 asbuilt I am not seeing anything immediately obvious that could fix this.
That’s not ringing any bells, but maybe @F150Chief or @NaviUpgrade could assist or confirm if there is not such a value.
You need to change the values in the APIM asbuilt for the APIM mounting position, since you flipped the APIM.
